Verify that quadrilateral bcde is a rhombus with vertices b(–2, 0), c(–7, 5), d(0, 6), and e( 5, 1) by showing that all four sides are equal.

Find the multiplicative inverse of 8-12i

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
